Today, music has become very portable in the form of digital music players such as the iPOD™. With 25% of Americans and 51% of American adolescents owning one of these devices, music is a familiar part of many lives (Pew, 2006). Pain studies evaluating musical interventions as auxiliary analgesia have used various types of music via different delivery systems (i.e. cassette/CD player with headphones, loudspeakers, live music by a music therapist) in different settings. Many of these trials have utilized self-selection of music and have included a variety of musical genres, specific sounds, white noise, and vocal suggestions. Although some studies indicate that slow and non-lyrical music of the patient's choice for at least 30 minutes at 60 decibel volume is ideal for optimal pain relief and relaxation, it is not known if these factors directly influence music's impact in reducing pain and anxiety (Nilsson, 2008).
